The Corsair Raptor M40 combines performance gaming features with the comfortable responsiveness of an optical mouse. The game tuned 4000 DPI optical sensor delivers accurate linear tracking—with no acceleration or predication—so every movement translates directly into game play. The adjustable weight system lets you fine tune both weight and balance to your playing style. On-the-fly DPI adjustments and seven fully programmable mouse buttons improve response time for faster shots and quicker escapes. Plus the right handed design includes key comfort features such as soft touch finishes, a low-friction braided cable and extended PTFE mouse feet to maximize your gaming experience.
